I am 35 yo white male, not smoker and lightly overweight with a past history of hypercalcium in urines and a bladder sclerosis (2 bladder stone removal operations).
During the last operation they found a cyst in my right kydney and asked me to follow up (but I do not remember the size!).
At the follow up they said that the cyst is 18 mm and has thick walls therefore a TC is required.
They added however that I should not be worried and stated that the chance that I have something bad is around 2%.
However I have read online that a thick-walled cyst has 50% of being malignant.
The TC is in 3 weeks and I am feeling VERY anxious.
Should I really not be that worried?
